Abstract: A system including a first circuit, a second circuit, and a third circuit. The first circuit receives a supply voltage and a timer signal and is configured to provide an output voltage that is greater than the supply voltage. The second circuit receives the output voltage and enables an output current if the output voltage is sufficiently greater than the supply voltage. The third circuit detects the output current and is configured to provide a load current and a feedback current in response to the output current. The first circuit receives the feedback current and a feed back loop including the first circuit and the second circuit and the third circuit regulates the output voltage and the load current via the feedback current.

Abstract: Systems for changing address information utilized by a network device, e.g., a fiber channel network device, are provided. Preferably, the system includes a control system that is configured to receive information corresponding to desired address settings of the network device. The control system is able to store information corresponding to the desired address settings of the network device and replace the current address settings with the desired address settings of the network device. So configured, a communications port associated with the network device may be recognized by the network as being associated with the current address. Methods, computer readable media, and graphical user interfaces also are provided.

Abstract: Devices for a Fibre Channel Arbitrated Loop are initially unconfigured, and during the first loop initialization, arbitrate as a soft addressed device. The chosen address is then stored in non-volatile memory. Once an address is stored in non-volatile memory, during subsequent loop initializations, the device arbitrates as a hard address device. Because the address was chosen during a standard Fibre Channel Loop Initialization Process, the risk of future hard address conflicts is greatly reduced. Preferably, however, firm addresses may be erased by operator control, or by system command. Firm addressing provides the fixed address benefits of hard addressing, but substantially reduces the risk of hard address conflicts, while remaining compatible with the ANSI standards for Fibre Channel.

Abstract: A solution to the problem of I/O card faults caused by spurious RF energy induced by ESD related currents in the vicinity of an aperture in a chassis is to reduce the efficiency of the radiating antenna created by the aperture and decouple any remaining spurious RF energy from any would-be receiving antenna in the I/O card. A conductive boot covers the I/O cable as it emerges from the chassis. The boot is physically attached and AC coupled (as well as probably ohmically connected) to the chassis at one end and tapers down to a small aperture at a distal end to permit egress of the I/O cable. The aperture at the distal end is considerable smaller than the aperture at the chassis, which is no longer visible to ESD induced currents anyway, since its edge has been replaced by the surface of the boot. The smaller aperture is a less efficient antenna at the frequencies of interest and it is now further removed from components that might act as receiving antennae.
